Ok, but the British also shortened television and made it tele. That makes sense because they took part of the word to do it. If you were going to shorten the word mathematics, why wouldn’t it be math, especially when that would follow what you did with television. Why shorten the word and then add the s from the end for no reason?

That may be, but Math still encompasses all Math so there’s no need to pluralize it.

I don’t understand why people say Maths. Math encompasses every single type of Math. Maths is just wrong.
